Sure thing! We've got 36 and we're gonna multiply it by 39. That's the same as adding 36 to itself 39 times.
Step 1: 0 + 36 = 36
Step 2: 36 + 36 = 72
Step 3: 72 + 36 = 108
Step 4: 108 + 36 = 144
Step 5: 144 + 36 = 180
Step 6: 180 + 36 = 216
Step 7: 216 + 36 = 252
Step 8: 252 + 36 = 288
Step 9: 288 + 36 = 324
Step 10: 324 + 36 = 360
Step 11: 360 + 36 = 396
Step 12: 396 + 36 = 432
Step 13: 432 + 36 = 468
Step 14: 468 + 36 = 504
Step 15: 504 + 36 = 540
Step 16: 540 + 36 = 576
Step 17: 576 + 36 = 612
Step 18: 612 + 36 = 648
Step 19: 648 + 36 = 684
Step 20: 684 + 36 = 720
Step 21: 720 + 36 = 756
Step 22: 756 + 36 = 792
Step 23: 792 + 36 = 828
Step 24: 828 + 36 = 864
Step 25: 864 + 36 = 900
Step 26: 900 + 36 = 936
Step 27: 936 + 36 = 972
Step 28: 972 + 36 = 1008
Step 29: 1008 + 36 = 1044
Step 30: 1044 + 36 = 1080
Step 31: 1080 + 36 = 1116
Step 32: 1116 + 36 = 1152
Step 33: 1152 + 36 = 1188
Step 34: 1188 + 36 = 1224
Step 35: 1224 + 36 = 1260
Step 36: 1260 + 36 = 1296
Step 37: 1296 + 36 = 1332
Step 38: 1332 + 36 = 1368
Step 39: 1368 + 36 = 1404

So, 36*39 = 1404
